Abstract
The present invention relates to comprise the resin dispersion of water, resin, tensio-active agent and caseinate.The invention still further relates to the method for this aqueous resin dispersion of preparation and the tackiness agent of preparing with this aqueous resin dispersion.
Description
The present invention relates to comprise the aqueous resin dispersion of water, resin, tensio-active agent and caseinate (caseinate).The invention still further relates to the method for this aqueous resin dispersion of preparation and the tackiness agent of preparing with this aqueous resin dispersion.
Resin dispersion can be by many kinds of method and apparatus manufacturings.They can comprise system and the solvent-free system (100% is water base) that full solvent system, solvent participate in.In full solvent system, resin dissolves is used in varsol and in solvent medium.In the system that solvent participates in, resin is dissolved in the varsol with the minimum quantity that reaches the promotion emulsifying effect and is added to the water immediately.
The contact tackiness agent generally not only needs to possess hot strength but also need to possess excellent contact (contactability).By using such resin dispersion can accomplish this point, promptly based on the high relatively resin of softening temperature, combine with low softening point resin and to improve contact, or improve intensity under the high temperature with a kind of resin-bonded of more high softening-point.But the preparation of this resin dispersion is difficult to carry out under the situation of not using varsol, and needs quite expensive supercharging dispersion system (pressurizeddispersing system).If the softening temperature of base resin surpasses 85 ℃, resin dispersion just must prepare under elevated pressure to prevent the water boiling in the dispersion.Such equipment is not only expensive but also complicated.
In addition, the emulsification particle diameter and the less resin that distributes need be selected examples of suitable emulsifiers system and equipment.This will become complicated along with the raising of resin softening point.Therefore, the particle diameter of many high softening point resin dispersions such as the terpenes phenoplast is bigger, often has bimodal particle size distribution and the very large particle of significant quantity is arranged.Big this feature of bimodal distribution and particle diameter has caused unstable, often shows as shelf-lives and shorten concerning these resin dispersions.And grit and condensation problem appear in these resin dispersion cognition.
So far, water base contact adhesive formulation has to make it the resin dispersion that (1) uses solvent to participate in, and makes the use of these materials become not satisfactory but the solvent of these materials causes regulating increase; (2) use the complicated blend of high and low softening temperature resin dispersion to obtain needed contact and do not destroy the hot strength performance; Or (3) are compared with solvent participation system with full solvent system and are produced the adhesive formulation that shows poor performance.
In the past, casein has been used as emulsifying agent and has been used for solvent-free system.The resin dispersion of casein emulsification is good tackifier for the polymkeric substance that is used in such as in the water base contact tackiness agent of sovprene.But, because biological attack and/or caseic Natural Degradation, the product of casein emulsification with compare not satisfactoryly with the resin dispersion of synthetic emulsifier production, the latter has suitable patience to microbiological deterioration.
Casein solution has been used to make resin dispersion at aqueous phase in the water-based resin dispersion.In this role, casein solution plays a major role as unique or main emulsifying agent and on the determining of particle diameter and distribution.Having caseic additional benefits in these resin dispersions is to have improved hot strength, and this product that can use from water base contact tackiness agent is seen.
In those resin dispersions of the dispersion of using casein formation aqueous phase or resin, caseic degraded causes dispersion partly or entirely to be destroyed.When as main tensio-active agent, in case casein is destroyed, resin dispersion also just destroys.When being used as main tensio-active agent, the caseic amount that is used in the dispersion is subjected to the mutually required quantitative limitation of dispersion resin.
The present invention is different from the traditional role of casein in resin dispersion, because the casein of caseinate soln form only plays a part performance additive.Because caseinate soln is inoperative or do not participate in the formation of the particle diameter of resin in dispersion to the dispersion of resin, caseinate soln influences the stability of the resin dispersion that it added not obviously.
The present invention is useful especially for water base contact tackiness agent, and this kind tackiness agent not only needs high-temperature behavior but also need good contact or combinableness.The personnel that are familiar with water base contact tackiness agent compounding process used multiple dispersion to obtain to possess the adhesive formula of contact and hot strength in the past.This method needs the plural equilibrium of low softening point and high softening point resin dispersion.Except the logistic problems of handling the various kinds of resin dispersion, the interaction that more complicated is between the kinds of surface promoting agent that is contained in the resin dispersion and they are to the influence of the tackiness agent that contains these dispersions.
The present invention not only provided the contact of the low softening point resin dispersion that needs and combinableness but also the hot strength that interrelates with the higher resin dispersion of softening temperature was provided in no solution system.
